The partial restoration of the NCCL will be performed prior the surgeries and will be carried out with composite resin.The surgical procedure for root coverage will be carried out by means modified coronally advanced flap and will be performed by starting with oblique incisions in the interdental areas, which continued with the intrasulcular incision at the recession defects.Each surgical papilla will be dissected in a split-thickness and the envelope flap will be raised with a split-full-split thickness in the coronal-apical direction. Additionally, this group will receive the connective tissue graft harvested from the palate on the recessed area before the sutures.Then, the flap will be coronally positioned and sutured to completely cover the graft.
